[The treatment results in children diagnosed with non-Hodgkin's lymphomas and acute B-cell lymphoblastic leukemias treated by the BFM protocols. The report of the POGM (Pediatric Oncology Group of Madrid)].

OBJECTIVE

The purpose of this study was to reproduce the results obtained by the "BFM Group" in children with NHL and B-ALL treated with BFM 86 and 90 protocols.

PATIENTS AND

METHODS

From April 1987 until January 1997, we have treated a total of 82 children, 22 with non-B NHL, 49 B-NHL and 11 B-ALL. Forty-four of them were treated according to BFM 86 and 38 according to BFM 90 protocols.

RESULTS

Ninety-four percent of the patients achieved complete remission (CR) and 15% of these relapsed, 12% of the cases of B NHL/ALL and 23% of the non-B NHL. The 5 year overall survival (Kaplan Meier) was 81% for the B NHL/ALL it was 83% and for non-B NHL 77%. The event-free survival was 75% for B-NHL, stages I and II it was 80% and stages II and IV 78%, for B-ALL 72% and for non-B NHL 68%. The median follow-up time was 50 months (12-106).

CONCLUSIONS

Treatment of NHL and B-ALL with BFM protocols is an effective therapeutic choice, with reproduction of the results of the "BFM group" being feasible.
